Title: Drive method for electron emitting element and image forming device
Inventor: HAMAMOTO YASUHIRO
IPC: H01J1/304
Filed: 1999-02-19
Abstract: PROBLEM TO BE SOLVED: To provide a highly reliable electron emitting element by suppressing quantity reduction of electrons emitted with elapse of time and instability of emission. SOLUTION: This electron emitting element is driven preliminarily to stabilize a quantity of electrons emitted, before it is normally driven. That is, a the relation between an electric current I and a voltage V in a voltage range to cause electron emission from the electron emitting element is expressed by a function I=f(V), and when f'(V) is defined as the differential coefficient of f(V) at a voltage V, the electron emitting element is normally driven by a voltage V2 which satisfies the inequality f(V1)/[V1.f'(V1)-2f(V1)]>f(V2)/[V2.f'(V2)-2f(V2)], after the electron emitting element is driven in advance by a voltage V1.

Title: Residual pressure mechanism for cylinder
Inventor: KUBOTA HITOSHI
IPC: B60T11/16
Filed: 1978-04-08
Abstract: PURPOSE: To apply residual pressure determined by a spring when a brake fluid is filled, by providing two one-way valves in the face of each other in a communication hole and applying the spring to the valves and evacuating air from a brake to leave no pressure.  
     CONSTITUTION: When air is evacuated from the assembled brake, air is introduced through a hole 15b of a check valve plug 15 to push up a second one-way valve 16. Tehn, the air passes throught a hole 13a of a valve retainer 13, pushes a first one- way valve 12 open and goes out through an opening 12a. The brake fluid introduced through a small hole 3b closes the first one-way valve 12 and moves it down together with the valve retainer 13. Then, the brake fluid flows from the hole 13a to the end of a brake system through an opening 16a of the second one-way valve 16. When a brake pedal is once depressed and returned, the brake fluid flows back in the same direction as the air evacuation. When the pressure of the fluid falls to be balanced to the force of the spring 14, the second one-way valve 16 is closed in contact with the plug 15 to leave set pressure in the brake system.

Abstract: PROBLEM TO BE SOLVED: To deposit a palladium catalyst by short-time exposure and to more effectively remove a photosensitive film in a cleaning stage, by using a hydrophilic activated catalyst contg. a lactate, a palladium salt and an alkali soln. SOLUTION: The hydrophilic activated catalyst soln. for electroless plating contg. a lactate, a palladium salt and an alkali soln. is applied on a substrate to form a photosensitive film consisting of the activated catalyst soln. by spin coating, etc. The photosensitive film is then irradiated with a light such as an electron beam to deposit a palladium catalyst on the substrate. Subsequently, the substrate coated with the palladium catalyst is dipped in an electroless plating bath to deposit an electroless plating film on the substrate with the palladium catalyst as the activated catalyst. In this case, since the activated catalyst soln. is hydrophilic, the photosensitive film is developed with water, the unnecessary protective film can be more completely removed, and the separability of the pattern of the plating film can be enhanced.

Abstract: PURPOSE:To supply a tabulation support device having a function which enlargement-operates a list in the direction of a row and enlargement-operates it in the direction of a column by means of a character input operation during tabulation. CONSTITUTION:A character inputted to an input part 1 is transmitted to an on-ruled line input judgement part 5 and a display content alteration part 2. The on-ruled line input judgement part 5 refers to the content of a ruled line holding part 4, judges whether the character is inputted on the ruled line or not, whereby it outputs a result. When the on-ruled line input judgement part 5 judges that input is not on the ruled line, the display content alteration part 2 alters the content of a character holding part 3 so that the input character is displayed in a place where input is executed. In such a case, the content of the ruled line holding part 4 is not altered. When the on-ruled line input judgement part 5 judges that input is executed on the ruled line, the content of the character holding part 3 is altered so that the input character is displayed in the place where input is executed and the content of the ruled line holding part 4 is altered, whereby the ruled line existing at the place where the character is inputted is shifted. At that time, a character string is simultaneously shifted for keeping the compatibility of display if necessary. An output part 6 displays the content of the character holding part 3 and that of the ruled line holding part 4 at last.
